Like DaimlerChrysler's system, V2V uses Wireless LAN (WLAN)
technology, GPS and a vehicle’s numerous computer controlled active safety
systems to relay data back and forth between vehicles. The system is capable of
relaying such data as Emergency Brake Warning, Blind Spot/Lane Change notification
(with accompanying blinking LEDs in the side view mirror and vibrating driver's
seat), Forward Collision Warning and Emergency Vehicle Warning (with location
and direction of travel for the emergency vehicle).

"Driving is a very complex task. Knowing where the
other guy is and where he’s headed can be as critical as being in control of
your own vehicle," said GM's Hans-Georg Frischkorn. "With V2V
technology, we intensify the driver’s awareness of his environment to improve
road safety, without any distraction to him and certainly without reducing his
level of control. This sixth sense lets drivers know what’s going on around
them to help avoid accidents and improve traffic flow."

Whereas DaimlerChrysler's system will be employed in
high-end Mercedes vehicles at first, GM is using off the shelf components to
drive down costs and implement the system on as many vehicles as possible.
